Can you do something really nice for yourself today? It would be good for you to get your mind off what HE is doing and just concentrate on YOU. Could you go see a movie? Get a pedicure? Take a walk near something beautiful?
I have been in a similar situation before, allowing someone to take up way too much space in my brain for waaaaay too long. I started working on myself, and learned how to accept myself for who I am. I got busy in Al Anon and made some good friends who helped me to keep the focus on myself. I had to learn about who I was, and then I learned about who I wanted to let into my life. When I wasn't in a good place, I attracted unhealthy partners. Now that I am in a much better place, so are the people with whom I choose to spend my time.
It's a lovely day. Enjoy it... you deserve it.
